Abstract:
Objective To explore the value of BI-RADS scoring system based on the sonographic features in the breast nodules.Methods In order to build a Logistic regression model,regression was made to analyse 401 patients ' sonographic features of breast nodules.A scoring system was developed based on the results of regression's filter and the weight of each factor,used to score and classify the other 243 patients.It's diagnostic value was evaluated through comparing all types of theoretic risk ranges of BI-RADS.Results Age,morphology,orientation,margin,echo pattern and microcalcifications in a mass were selected in the final step of the logistic regression analysis.By means of scoring system,the scores corresponding to BI-RADS 3,4a,4b,4c,5 classes are 6,7-8,9-15,16-22 and ≥23 respectively.Case study comprehensive score of BI-RADS 3-5 classification' s positive predictive values were 0,4.17％,21.43％,84.85％,1 00％,and the area under the ROC curve scoring system was 0.947.Conclusions The scoring system can objectively score and classify breast nodules,and therefore provide an effective reference for clinical evaluation of benign and malignant breast.
